(Hope multiple questions/topics is okay for one ask)
1- What animal do you think would make the best fit for Isaac's spiritual animal/companion?
2- Despite Mike giving off "well-meaming but clueless grandpa" vibes, I think Izzy would get along with him if given enough time
3- I also like the headcanon that Izzy is partially Brazilian, though maybe that's just the bias of being Portuguese (and even then I'm not saying if I'm from mainland Portugal or the islands), but my personal assumption is that Isaac is half Brazilian on his mom's side and half Panameño (Panama) on his dad's side
3.5- I say Panama rather than the Dominican Republic, Chile, Mexico or others because I think it'd be a funny test for Izzy, since El Dia de los Muertos in Panama is celebrated much differently than in other countries who include it as a holiday, because instead of it being festive, it's a solemn "Dry Day" of remembrance, so no alcohol is allowed in respect for dead ancestors
4- Do you think Izzy would support Leah and Cassie if the Vibes™ turned out to be canon/semi-canon?
i've always associated him w/ honey badgers! mostly bc of the way honey badgers are known for punching above their weight and standing up to/surviving attacks from far bigger & stronger animals. like despite isaac's anxiety issues, this is still a guy who survived Thee Devil jumping him, and then proceeded to defeat Thee Devil
isaac gets along with most people by default, so i can definitely see that! i also think mike might be slightly less standoffish w/ isaac since he knows isaac played a key part in how he got out of the Nightmare Sand Pit
thats the second time someone's headcanon'd him as brazilian lol which is kinda fascinating since i didn't really have a particular place of familial origin in mind when i was designing him? i wonder what it is abt him that seems to have stumbled upon strong brazilian vibes
interestingly enough the dominican republic was another option i considered before deciding to keep his birth family's origin vague (and like i said in the tags of that other hc ask, don't take that as canon lol)
absolutely! i think by the time they could possibly get together (i'm thinking of having PYHA's sequel happen in 2014) isaac no longer gets that envy abt other's romantic successes like he had towards joshline. which isn't entirely positive character growth, since it stems from him assuming he'll never have the kind of long-term friends with benefits relationship he actually wants and instead settling for one night stands ;_;
